SCR-1

Silicon Controlled Rectifier

TS820-700T NTE5438

D2 P600M 6A10

The SCR rectifier is normally OFF

• A positive voltage on the Gate will turn it ON
• if the Anode is positive and the cathode is negative

• Once turned ON, the gate no longer has control.
• It will stay ON until the voltage is removed, reversed, or current drops below the holding current.

• This works well with AC voltage, because it turns OFF on every cycle.
• It also works on pulsating DC
